Our corporate and commercial litigation team has handled some of the most high-profile cases of the last ten years.

Our lawyers handle strategic international corporate litigation, and frequently work with a worldwide network of partner lawyers.

Our practice focuses on three main areas:
  • equity financing and corporate governance litigation (post-acquisition disputes - seller's warranties, price adjustments and earn-outs, accusations of fraud - shareholder disputes, unfair dismissal, and liability of corporate officers),
  • contractual and tort litigation (breach of contract, unfair commercial practices, unfair termination of commercial relations, enforcement actions, contractual liability, etc.),
  • industrial litigation: in collaboration with our team of patent attorneys and engineers, we occupy a unique position in the market (product liability, latent defects, industrial accidents, classified and protected sites, supply chains, etc.).
According to our clients' needs, we analyze the most advantageous method of dispute resolution and promote alternatives to litigation where appropriate. In order to resolve disputes in an effective and sustainable manner, we also advise our clients in the course of amicable procedures such as conciliation or mediation.
Our white-collar team has developed recognized expertise in handling difficult cases with significant political and media implications. We defend companies, executives, and prominent public figures who are under investigation, facing prosecution, or acting as civil parties in complex cases involving various types of economic offenses (insider trading, corruption, misuse of corporate assets, money laundering, market manipulation, tax fraud, and international sanctions).

Our experience in internal investigations and transnational proceedings, combined with our robust network of partner firms, enables us to support our clients in sensitive cases abroad. Our team operates before French criminal courts as well as before foreign prosecuting authorities (such as the Department of Justice and the Financial Crimes Enforcement Network in the United States, and the Serious Fraud Office in the United Kingdom). We conduct internal investigations and defend our clients before courts and regulatory bodies both in France and internationally.

Our expertise also extends to employment, competition, criminal, and environmental restructurings.

We act for various stakeholders, including debtors, shareholders, financial creditors, and potential buyers.
